1-2 HANDLING THE MOTHERBOARD
To avoid damage to your Motherboard, follow these simple rules
while unpacking:
ØBefore handling the Motherboard, ground yourself by grasping
an unpainted portion of the system's metal chassis.
ØRemove the Motherboard from its anti-static packaging. Hold
the Motherboard by the edges and avoid touching its
components.
ØCheck the Motherboard for damage. If any chip appears loose,
press carefully to seat it firmly in its socket.
Warning: Do not apply power if the Motherboard appears
damaged. If there is damage to the board, contact your
dealer immediately.
1-3 ELECTROSTATIC DISCHARGE PRECAUTIONS
Make sure to ground yourself before handling the Motherboard or
other system components. Electrostatic discharge can easily
damage the components. Note that you must take special
precautions when handling the Motherboard in dry or air-conditioned
environment.
To protect your equipment from electrostatic discharge, take the
following precautions:
ØDo not remove the anti-static packaging until you are ready to
install.
ØGround yourself before removing any system component from its
protective anti-static packaging. (To ground yourself, grasp the
expansion slot covers or other unpainted portions of the computer
chassis.)
ØFrequently ground yourself while working or use a grounding strap.
ØHandle the Motherboard by its edges and avoid touching its
components.

HARDWARE SETUP
Congratulations on your purchase of SY-6BA+ Motherboard. You
are about to install and connect your new Motherboard.
Note: Do not unpack the Motherboard from its protective
anti-static packaging until you have made the following
preparations.
2-1 PREPARATIONS
Gather and prepare all the following hardware equipment to
complete the installation successfully:
1. Slot 1 processor with built-in CPU cooling fan (boxed type).
Note: This Motherboard supports non-boxed type CPUs. The
heavier CPU cooling fan requires the installation of a CPU
support stand.
2. DIMM memory module
3. Computer case and chassis with adequate power supply unit
4. Monitor
5. PS/2 Keyboard
6. Pointing Device (PS/2 mouse)
7. Speaker(s) (optional)
8. Disk Drives: HDD, CD-ROM, Floppy drive…
9. External Peripherals: Printer, Plotter, and Modem (optional)
10. Internal Peripherals: Modem and LAN cards (optional)

2-2 UNPACKING THE MOTHERBOARD
When unpacking the Motherboard, check for the following items:
ØThe SY-6BA+ 82440 BX AGP/PCI Motherboard
ØThis Quick Start Guide *
ØThe Installation CD-ROM *
ØOne IDE Device Flat Cable
ØOne Floppy Disk Drive Flat Cable
* If your board comes with a driver disc and a paper manual, the Quick Start Guide
and the CD-ROM are not included in the package.
Warning: Do not unpack the Motherboard from its anti-
static packaging until you are ready to install it.
Like most electronic equipment, your Motherboard may be damaged
by electrostatic discharge. To avoid permanent damage to
components ground yourself while working by using a grounding
strap. Otherwise, ground yourself frequently by touching the
unpainted portion of the computer chassis to drain the static
charges.
Handle the Motherboard carefully, holding it by the edges.
You are now ready to start the installation.

2-3 INSTALLATION GUIDE
We will now begin the installation of the Motherboard. Please follow
the step-by-step procedure designed to lead you to a complete and
correct installation.
Warning: Turn off the power to the Motherboard, system
chassis, and peripheral devices before performing any
work on the Motherboard or system.
BEGIN THE INSTALLATION
Step 1. CPU Installation
Your SY-6BA+ motherboard comes with a CPU retention set kit. The
retention set is used to hold the processor attached to the Slot 1
CPU connector on the motherboard.
Follow these instructions to install your Slot 1 processor correctly.
ØRetention Module

1. Open the two sides by folding them up.
2. Push the locks on top of the CPU inward.

Hardware Setup SY-6BA+

3. Insert the CPU into the retention module. The CPU fits in the CPU slot
in only ONE way, do not try to force it in.
4. After completely inserting the CPU, push the two locks on top of the
CPU outward. Now your CPU is ready for use.
To remove the CPU, press the two notches on top of the CPU
inward. Now press the two slides on the retention module down
and remove the CPU.

Hardware Setup SY-6BA+
11
Note: Installing a heat sink and cooling fan on top of your
CPU is necessary for proper heat dissipation. Failing to
install these items may result in overheating and possible
burn-out of your CPU.
Step 2. CPU Fan Installation
Your Slot 1 processor kit comes with a cooling fan. Mount the fan on
the processor according to the instructions provided by the
manufacturer. The fan is a key component that will ensure system
stability. The fan prevents overheating, therefore prolonging the life
of your CPU.
Note: Remember to connect the fan to the appropriate power
source.

Step 3. SDRAM Memory Module Installation
This Motherboard features 4 x DIMM Banks for 168-pin 3.3V
unbuffered and registered DIMM modules. Your board comes with
four DIMM sockets, providing support for up to 1GB of main memory
using DIMM modules from 8MB to 256MB. For 66MHz front side bus
CPUs use 12ns or faster memory; for 100MHz front side bus CPUs
use 8ns (100MHz, PC100 compliant) memory.

Note: (1) 256 MB memory modules available on PC registered DIMM only.
(2) Always install memory modules in the order prescribed in this table.
(3) Do not install unbuffered and registered memory modules together.
Important: It is of prime importance that you install DIMM modules
as outlined in the table above in order to preserve signal integrity on
100MHz front side bus systems.

Step 4. IDE Device Installation (HDD, CD-ROM)
This Motherboard offers two primary and secondary IDE device
connectors (IDE1, IDE2.) It can support up to four high-speed HDD
or CD-ROM.
Connect one side of the 40-pin flat cable to the IDE device (HDD or
CD-ROM) and plug the other end to the primary (IDE1) or secondary
(IDE2) directionally keyed IDE connector on the Motherboard.
This Motherboard can support up to four HDDs.
Step 5. Floppy Drive Installation
The system supports 5 possible floppy drive types: 720 KB, 1.2 MB,
1.44 MB, 2.88 MB, and LS-120. In addition, this Motherboard
supports a 3-mode (720KB/1.2MB/1.44MB) floppy commonly used
in Japan.
Connect one side of the 34-pin flat cable to the floppy drive and plug
the other end to the floppy drive connector on the Motherboard.
This Motherboard can support up to 2 floppy drives.
